Anyone who sees it, will try to touch the floating image - it seems so real! 16 cms in diameter and black in color, this hologram chamber makes a great fun desktop curiousity. Complete with perfect floating replicas of both the TARDIS and Daleks.

Following Cyberman
An illusion where the Cybermen appear to follow you around the room! Our brain makes assumptions when we view ther Cyberman's face, it thinks it should appear like a typical convex face that it has experience of. However, in this case, that is not true, as the face is actually concave. Our brain cannot understand this and as a result, a rather strange illusion takes place where it appears that the Cyberman is following us round the room! Requires 3 x AA batteries.
